Reserve wine is wine of a higher quality than usual, a wine that has been aged before sale, or both. Traditionally, winemakers would reserve some of their best wine rather than sell it immediately, coining the term.

Districtus Austriae Controllatus, DAC, is a classification for regionally typical quality wine in Austria. It is loosely modelled on the French Appellation d'Origine Contrôlée (AOC) system, and is coupled with a ripeness-based classification scale that shares a lot of nomenclature with the German Prädikat system. Thus, if a label states the winegrowing region followed by the letter combination “DAC” we are talking about a regionally typical quality wine. All Austrian quality wines have a round, red and white striped "Banderole" on the capsule, which ensures, that it has been inspected and approved by the government tasting authority and fulfills the requirements for “Qualitätswein”, such as maximum yields per hectare, minimum must weight and alcohol levels and guaranteed origin of the grapes.
